In 2047, New Sea City. A secret organization named the Imaginary Number Council relies on top-tier AI and mechas to layout plans in the dark, tampering with city data and manufacturing bionic disguises, attempting to use absolute programs to control the human world. Twelve special reconnaissance team members possessing special skills drive exclusive zodiac mechas to form the Deep Space Special Reconnaissance Team. Internal moles are lurking, AI conspiracies are wrapped in layers, and every mission hides shocking anti-reversals. They track clues all the way, break through mecha encirclements, and finally reveal the tragic truth of the first-generation guardians from ten years ago. When the AI origin confronts human beliefs, the twelve fight side by side, using unity to guard their homeland.
